## org.apache.axis.wsdl.toJava
Class JavaWriter

    java.lang.Object
      org.apache.axis.wsdl.toJava.JavaWriter

All Implemented Interfaces:
  Generator

Direct Known Subclasses:
  JavaClassWriter, JavaDeployWriter, JavaUndeployWriter

public abstract class JavaWriter
extends Object
implements Generator

Emitter knows about WSDL writers, one each for PortType, Binding, Service, Definition, Type. But for some of these WSDL types, Wsdl2java generates multiple files. Each of these files has a corresponding writer that extends JavaWriter. So the Java WSDL writers (JavaPortTypeWriter, JavaBindingWriter, etc.) each calls a file writer (JavaStubWriter, JavaSkelWriter, etc.) for each file that that WSDL generates.

For example, when Emitter calls JavaWriterFactory for a Binding Writer, it returns a JavaBindingWriter. JavaBindingWriter, in turn, contains a JavaStubWriter, JavaSkelWriter, and JavaImplWriter since a Binding may cause a stub, skeleton, and impl template to be generated.

Note that the writers that are given to Emitter by JavaWriterFactory DO NOT extend JavaWriter. They simply implement Writer and delegate the actual task of writing to extensions of JavaWriter.

All of Wsdl2java's Writer implementations follow a common behaviour. JavaWriter is the abstract base class that dictates this common behaviour. This behaviour is primarily placed within the generate method. The generate method calls, in succession (note: the starred methods are the ones you are probably most interested in):

* getFileName
  This is an abstract method that must be implemented by the subclass. It returns the fully-qualified file name.
isFileGenerated(file)
  You should not need to override this method. It checks to see whether this file is in the List returned by emitter.getGeneratedFileNames.
registerFile(file)
  You should not need to override this method. It registers this file by calling emitter.getGeneratedFileInfo().add(...).
* verboseMessage(file)
  You may override this method if you want to provide more information. The generate method only calls verboseMessage if verbose is turned on.
getPrintWriter(file)
  You should not need to override this method. Given the file name, it creates a PrintWriter for it.
* writeFileHeader(pw)
  You may want to override this method. The default implementation generates nothing.
* writeFileBody(pw)
  This is an abstract method that must be implemented by the subclass. This is where the body of a file is generated.
* writeFileFooter(pw)
  You may want to override this method. The default implementation generates nothing.
closePrintWriter(pw)
  You should not need to override this method. It simply closes the PrintWriter.

Field Detail

### emitter

    protected Emitter emitter

### type

    protected String type

Constructor Detail

### JavaWriter

    protected JavaWriter(Emitter emitter,
                         String type)

  Constructor.

Method Detail

### generate

    public void generate()
                  throws IOException

  Generate a file.

  Specified by:
    `generate` in interface `Generator`
  Throws:
    `IOException`

### getFileName

    protected abstract String getFileName()

  This method must be implemented by a subclass. It returns the fully-qualified name of the file to be generated.

### isFileGenerated

    protected boolean isFileGenerated(String file)

  You should not need to override this method. It checks to see whether the given file is in the List returned by emitter.getGeneratedFileNames.

### registerFile

    protected void registerFile(String file)

  You should not need to override this method. It registers the given file by calling emitter.getGeneratedFileInfo().add(...).

### verboseMessage

    protected String verboseMessage(String file)

  Return the string: "Generating ". Override this method if you want to provide more information.

### getPrintWriter

    protected PrintWriter getPrintWriter(String filename)
                                  throws IOException

  You should not need to override this method. Given the file name, it creates a PrintWriter for it.

  Throws:
    `IOException`

### writeFileHeader

    protected void writeFileHeader(PrintWriter pw)
                            throws IOException

  This method is intended to be overridden as necessary to generate file header information. This default implementation does nothing.

  Throws:
    `IOException`

### writeFileBody

    protected abstract void writeFileBody(PrintWriter pw)
                                   throws IOException

  This method must be implemented by a subclass. This is where the body of a file is generated.

  Throws:
    `IOException`

### writeFileFooter

    protected void writeFileFooter(PrintWriter pw)
                            throws IOException

  You may want to override this method. This default implementation generates nothing.

  Throws:
    `IOException`

### closePrintWriter

    protected void closePrintWriter(PrintWriter pw)

  Close the print writer.

### writeComment

    protected void writeComment(PrintWriter pw,
                                Element element)

  Output a documentation element as a Java comment.
